Footwear upper portion



FIG. 1 is a front end view of a footwear upper portion, showing my new design;

FIG. 2 is a right side view thereof;

FIG. 3 is a top view thereof;

FIG. 4 is a rear end view thereof; and,

FIG. 5 is a left side view thereof.

The broken-line showing of the sole and a lower and rear portion of the upper of the shoe is for illustrative purposes only and forms no part of the claimed design. 

I claim the ornamental design for a footwear upper portion, as shown and described.
